July 21, 2009 – Cloud Computing with Hadoop, Map/Reduce and Cascading


Cloud Computing is one of the most popular and abused terms in technology today. Rather than trying to explain all the different meanings and abuses of the term, I will be presenting on a specific technology that most developers can understand and use today, Map/Reduce.

Made famous by Google as the solution to ‘how to index the Internet 6 times a day’, the map/reduce paradigm is applicable to a surprising number of business challenges in organizations of all types. I will be talking about the Apache solution, Hadoop ([]) and a very interesting abstraction layer on top of Hadoop, Cascading ([])

Data Microservices with Spring Cloud Stream, Task, and Data Flow

Tuesday, July 19, 2016

Microservice based architectures are not just for distributed web applications! They are also a powerful approach for creating distributed stream and batch processing.

Spring Cloud Data Flow enables you to create and orchestrate standalone executable applications that communicate over messaging middleware such as Kafka and RabbitMQ that when run together, form a distributed stream processing application. It also allows users to create and orchestrate short lived microservices like batch jobs or boot applications that perform a task and then terminate when complete.

This allows you to scale, version and operationalize stream processing and task applications following microservice based patterns and practices on a variety of runtime platforms such as Cloud Foundry, Apache YARN and others.
